Q: "we couldn't create a new partition" 8.1 installation screen, iMac 5k
Well, here we are again.
I'm using an iMac 5k with a fusion drive. I'm trying to install Windows 8.1 and I'm getting the dreaded "we couldn't create a new partition" error during the windows installation screen. I also tried the format option within the windows installation partition screen. I ran into the issue before and instead used an Windows Enterprise ISO without any problems. Well that expired and now I'm back to using 8.1 Professional with a valid key. I also used a valid ISO retrieved from Windows. I didn't do anything to interrupt the Bootcamp assistant process. It wouldn't through the EFI drive. Can someone help me? Also can someone answer why this issue is prevalent through the iMac 5ks?
I'm using a USB 2.0 drive. Nothing else is plugged in.
